Securing Exchange 2010 with Forefront Threat Management Gateway (TMG) 2010, Part 4 - Installing Forefront Threat Management Gateway

Here we are, Part 4 of the series. To recap what I have done thus far.. I’ve installed the Exchange Server Edge role followed by Forefront Protection 2010 for Exchange Server.

In this part I install TMG 2010 and perform some basic configuration. The minimum system requirements for TMG 2010 can be found on Microsoft TechNet.

To get started, insert your Forefront Threat Management Gateway 2010 installation media and then select “Run Preparation Tool”

This launches the “Forefront TMG Preparation Tool”, read through the notes on the welcome screen and click “Next”. Read and accept the License Agreement and click “Next”

Depending on your environment, select the appropriate Installation Type. I won’t be installing a TMG array so I selected “Forefront TMG services and Management”. Then click “Next”

Once all the prerequisite features have been installed, click “Finish” to launch the TMG 2010 installation wizard.

Click “Next” on the welcome screen. Read and accept the License Agreement and click “Next”

Next you will be presented with the “Customer Information” page with the Product Serial Number. Once you have entered the appropriate details, click “Next” and verify the installation path. Change this as appropriate and click “Next”

Next we need to define our internal network ranges. Be sure to include all of them there, mine are fairly simple and are all included in the range 172.0.0.0-172.0.0.255.
